Abstract M–Co $${\mathrm{Fe}}_{2}{\mathrm{O}}_{4}$$ Fe 2 O 4 (where M=Cu and Zn) nanoferrites were successfully prepared using the citrate auto-combustion technique. The main idea was drawn through a complete study of structural, morphological, thermal, magnetic, electrical properties. obtain findings explained in light incorporation both $${\mathrm{Cu}}^{2+}$$ Cu + $${\mathrm{Zn}}^{2+}$$ Zn ions Co crystal. All investigated samples found to belong space group (Fd-3m) number (227). crystallite size , Cu–Co Zn–Co nanoparticles be 8, 15, 14, respectively. While, lattice constants 8.4 nm, 8.39 8.42 doping exhibits enhancement elastic shows young’ modulus at 278.97 GPa, while shear 185.98 as highest obtained values compared virgin other samples. saturation magnetization observed for sample, (56.1 emu/g) it being 46.9 45 emu/g magnetic susceptibility (0.639) . thermal conductivity, diffusivity, specific heat by hot disk technique room temperature. results have shown an properties -doped Zn Cu rather than predicting required stability working devices. sample value conductivity (0.95 W/m k), diffusivity (0.75 m $${\mathrm{m}}^{2}$$ m /s), (0.85 Mj/ $${\mathrm{m}}^{3}$$ 3 k) (0.6 0.82 (0.52 0.6 (0.62 0.72 permittivity all ferrite enhanced augmenting achieved sample. present offer decent contender material with appealing characteristics suitable different electronic applications.
